SYSTEM FOR HANDLING PRINTING-CYLINDERS.

SPECIFICATION forming para of Letters Patent No. 637,584, dated November 21,1899.

Application led January 3, 1899. Serial No. 700,925. (No model.)

To ctZZ whom, it wtf/,y concern:

Be it known thatl, EDWARD HETT, a citizen of the United States, and a resident of'New York, (NeWDorp,) in the count-y of Richmond, State of New York, have invented a certain new and Improved System for Handling Printing-Cylinders, of which the following is a specification.

My invention relates to printing and transfer presses, and particularly to devices for handling printing-cylinders or printing-tubes in connection with such presses.

It has for its object the rapid, ready, and convenient handling of printing cylinders or tubes o r supports therefor, particularly in connection with their introduction into and removal from operative position in the press.

It consists of the novel devices herein shown and described.

The preferred form of my invention, which is shown in the drawings herein, is shown in connection with a multicolor-press, although obviously it can be used with any kind of printing or transfer press in which printing cylinders, tubes, or supports therefor are used.

In the accompanying drawings, which form a part hereof and which show the preferred form of my improved device and in which the same reference characters in the different :figures refer to corresponding parts, Figure l is a View showing in a diagrammatical manner the electric circuits used in connection lwith and for the purpose of controlling the movements of the movable carriage and its operative parts. able carriage. Fig. 3 is a side view of the same. Fig. 4 is a side view of a multicolorpress, showing my improved devices applied thereto; and Fig.r 5 is a detail of part of my improved device. Fig. 6 is a diagram illustrating the circuit through the fields of the motor and certain modifications in the circuits.

Referring to the specific forms of apparatus shown in the drawings, 1 indicates the frame of a multicolor-printing press, of which 2 is the im pression-drum and 3 3 are the printingcylinders in position in the press.

4 4 are brackets pendent from the ceiling or other suitable support. These brackets are arranged on both sides of the press and Fig. 2 is a plan ofthe mov-- Vmade of any suitable construction. one end of shaft 16 is bevel gear-wheel 19,

support or carry rails 5, which are provided at one side With rack-teeth 6, as shown in Fig. 4. A movable carriage 7 is arranged to run upon rails 5 and is provided with a number of wheels 8, which bear upon the rails both upon the upper and the under side. One set of these wheels is provided with a Wheel having teeth to t into the racks 6. This set of Wheels I have designated as 8a. By means of these wheels the carriage is adapted to move along the rails 5 and rack 6, so that it can be brought into any position.

The carriage is provided with suitable hoisting-arms 9, which are adapted to be lowered and raised and are adapted to seize and to raise or lower printing-cylinders or printingtubes and their supports. Any suitable form of hoisting-arms andany suitable mechanism for raising and lowering them may be employed. As these form no part of my present invention, I will not further describe them herein, except to say that the hoisting-arms Vshown in the drawings are made substantially like the hoistingar1ns shown and described in an'application executed and filed by me simultaneouslyherewith and known as Serial 'No. 700,924 for an improvementin tube-handling devices. Fig. 3 represents the hoistingarms as carryinga printing-cylinder 10. In practice the movable carriage is moved forward and backward along the rails to the proper position and the hoisting-arms are lowered to introduce a printing-cylinder in proper position in the press or to withdraw it from such position. v

Movable carriage 7 is moved along the rails and motion is also imparted to the hoistingarms by means of an electric motor 11,mount ed upon the framework of the carriage. This motor may be of any suitable.construction. It is driven in the manner presently to be described. Upon the shaft 12 of the motor is mounted a gear-wheel13. (See Figs. land 2.) This gear-wheel meshes with large gearwheel 14, mounted upon a sleeve 15, which runs loosely upon shaft 16. Also mounted upon the same sleeve 15 are gear-wheelsl? and one part 18a of clutch 18. The other part 1Sb of the clutch 18 is fast upon shaft 16. Clutch 18 is an electric clutch and. can be Upon 2 f caisse meshing with bevel gear-wheel 20 on shaft 21, the latter shaft carrying Worm 22 atits other end, which meshes `with worm-wheel 23 on shaft 24. Attheend of the shaft 24 is toothed wheel 8", which meshes with teeth of rack 6. When the motor 11 is running, motion is imparted to the movable carriage by energizing electric clutch 18, thus causing shaft 16 to rotate with gear-wheel 14 and through the bevel-gears, the worm, and worin-wheel driving toothed wheel 8 and moving the carriage alongthe rails. Clutch 18is energized and deenergized in the manner presently to be described. Motion is imparted to the hoistingarms by means of the following-described mechanism: Gear-wheel17 meshes with gear- Wheel 25, mounted on short shaft 26, turning in bearings 27. Gear-wheel 25 also meshes with gear-wheel 28, loosely mounted on shaft 29. The same sleeve 30 which carries gearwheel 28 also carries part 31"L of clutch 31. The other part 31b of the clutch is fast upon shaft 29. Shaft 29 carries at each end bevel gear-wheels 32. Each of these bevel gearwheels meshes with a bevel gear-wheel 33, which is on a screw 34, which drives hoistingarm 35. The details of the mechanism by which this is accomplished form no part of my present invention and are therefore not described in further detail.

By energizing clutch 31 when the motor is running motion is imparted to the hoistingarms. Motion of the carriage one Way or the other and motion of the hoisting-arms up or down are determined by means of a reversingswitch, which determines the rotation of the motor one way or the other, as desired, in the manner presently to be described.

I will now proceed to describe the electric circuits by means of which the motor is driven in one direction or the other and howthe different clutches are energized to drive the carriage one way or the other on the rails and how the hoisting-arms are operated.

I place the motor and each of the electric clutches each in an electric circuit containing a circuit-controller which is underthe control of the operator. Preferably I place the circuit-controller under the control of the operator by means of a separate and distinct circuit, which, for convenience, I herein designate as an operating-circuit. This operating-circuit is controlled by the operator touching, preferably, a push-button. Each circuit-controller is opened, preferably, by the operator closing a releasing-circuit containing a magnet, which withdraws a catch which held the circuit-controller in closed position. The operator closes the releasing-circuit preferably by touching another push-button. The electricmotor is thus energized or dencrgized, and each electric clutch is energized or denergized at Will by merely touching the appropriate push-button, and the direction of rotation of the motor is determined by an ordinary reversing-switch.

I will now proceed to describe my preferred devices for accomplishing the above purposes.

37 is a switch, of any ordinary construction, for connecting or disconnecting with any suitable source of electrical supply.

38 39 are wires which connect the switch with suitable metallic strips 40 4l, suitably secured to rails 5 and insulated therefrom in any appropriate manner. Strip 41 is connected by wire 42 with one of the binding-posts of reversing-switch 43 and strip 40 is connected by wire 44 with another binding-post of the same reversing-switch. This reversingswitch is of any ordinary construction and is so arranged as to reverse the current by turning the switch.

The circuit through electric motor 1l is as follows: from the source of electrical supply, through switch 37, wire 38, strip 40 on one of the rails 5, wire 44, reversing-switch 43, Wire 45, contact-point 46, bridge 47 of circuit-controller 48, contact-point 49, wire 50, motor l1, wire 51, contact-point 52, bridge 53 of circuitcontroller 48, contact-point 54, wire 55 to the other side of the reversing-switch 43, Wire 42, strip 41, wire 39, back to switch 37, to the other wire of the source of electrical supply. This circuit is normally broken at circuit-controller 48. This circuit-controller is placed under the control of the operator. It is closed by him by pushing in push-button 56. This closes a circuit through magnet 57. For convenience this circuit and said magnet will thaty said switch is set, and then through wire,

42 or wire 44 to one side or the other of switch 37, also from push-button 56, through wire 59, wire 45, to the other side of the reversingswitch, and thence to the opposite side of switch 37. The pushing in of push-button 56 thus closes the operating-circuit through magnet 57 and closes circuit-controller 48. This closes the circuit through the motor.

As the pressing upon button 56 would ordinarily be but momentary, I provide means for holding circuit-controller 48 in its closed position. This mechanism consists of a catch 60, which locks circuit-controller 48 in its closed position, holding it in this position until the catch is removed, as hereinafter described. The motor is stopped by the operator pressing upon a push-button 6l, which closes a circuit through magnet 62. For convenience this circuit and magnet will be spoken of herein as the releasing-circuit and the releas- Icov The

ing-magnet. The releasing-circuit consists, preferably, of the following: wire 63, running from one side of the push-button 61 and connecting with wire 59, thence through wire 59, wire 45 to one side of the reversing-switch, from the other side of push-button 61, through Wire 64, wire 65, releasing-magnet 62, wire 66, releasing-magnet 67, wire 68, releasingmagnet 69, wire 70, part of wire 51, contactpoint 52, bridge 53, contact-point 54, Wire 55, to the other side of the reversing-switch. By pressing upon push-button 61 the operator thus energizes releasing-magnets 62 67 69, and,an1ong other things, withdraws catch 60 from operative connection with circuit-controller 48, permitting that circuit-controller to fall back into its normal open position. It will of coursebe understood that circuit-controller 48 is kept in its open position by springs or other suitable devices for that purpose. The operator can thus at will, by pressing upon push-buttons 56 or 61 and by turning the reversing-switch 43 one way or the other, cause motor 11 to rotate in one direction or the other or to cease from rotation.

Clutch 18 is energized and denergized in the following manner: For the purpose of controlling this clutch I also employ a circuit containing a circuit-controller, preferably normally open, which is under the control of the operator through an operating circuit and magnet, the latter being closed by pressing upon a push-button, being held closed by means of a catch, and the catch being released through a releasing circuit and magnet, which are respectively closed and energized by pressing upon another push-button, substantially in the manner described above for the circuits employed in connection with the motor. These circuits are as follows: The circuit through clutch 18 passes through wire 71, contact-points, and one of the bridges of circuit-controller 72, wire 73, to wire 44, thence to one side of switch 37 also from clutch 18 through wire 74, through contactpoints and the other bridge of circuit-controller 72 and wire 75 to wire 42, and thence to the other side of switch 37. The operating-circuit is as follows: Push-button 76, Where the circuit is normally broken, Wires 77 and 73 to wire 44, and thence to one side of the' switch 37; also from push-button 76 to wire 78, to operating-magnet 79, wire 75, to wire 42, and thence to the other side of switch 37. By depressing push-button '76 the operator energizes magnet 79, closing circuit-con- Catch 80 seizes and holds this circuit-controller in its closed position until released by releasing-magnet- 69. The releasing-circuit through the magnet 69 is as follows: Push-button 81, wire 82, wire 65, magnet 62, wire 66, magnet 67, wire 68, magnet 69, wire 7 0, part of wire 51, contact-points and one of the bridges of circuit-controller 48, wire 55 to one side of reversing-switch 43; also from push-button 81 through wire 83, wire 84, wire 59, wire 45 to the other side of reversing-switch 43. By pressing upon pushbutton 81 the operator thus energizes releasing-magnet 69, as well as releasing-magnets 67 and 62, and, among other things, withdraws catch 80 from operative connection with circuit controller 72, permitting that circuit-controller to fall back into its normal open position, thus breaking circuit through clutch 18 and denergizing thatclutch. The operator can thus at will, by pressing upon push-buttons 76 or 81, cause clutch 18 to be energized or denergized, thus causing the carriage to be driven along the rails or to stand still. By means of reversing-switch 43 the direction of motion of the carriage one Way or the other upon the rails can be controlled through the reversal of the direction of rotation of the motor. Y

Clutch 31 is energized and denergized in the following manner For the purpose of controlling this clutch I employ a similar circuit and circuit-controller and a similar operating circuit and magnet, and asimilar catch and releasing circuit and magnet, and similar pushbuttons. These circuits are as follows: The circuit through clutch 31 passes through wire 85, one set of contact-points and bridge of circuit-controller 86, wire 87, wire 44, strip 40, wire 38 to one side of switch 37; also from clutch 31, thro'ugh wire v88, the other set of contact-points and bridge of circuit-controller 86, wire 89, Wire 42, strip 41, and wire 39 to the other side of switch 37. The operatingcircuit is as follows: Push-button 90, where the circuit is normally broken, wires 91 and 87, wire 44, strip 40, wire 38, to one side of the switch 37; also from push-button 90, Wire 92, operating-magnet 93, wire 89, wire 42, strip 41, wire 39, to the other side of switch 37. By depressing push-button 90 the operator energize-.s operating-magnet 93, closing circuit-controller 86, and thus closing the circuit through clutch 31. Catch 94 seizes and holds circuit-controller 86 in its closed position until released by releasing-magnet 67 in the following manner: The releasing-circuit through this magnet is as follows: Push-button 95,wire 96,wire 65, magnet 62,wire 66,mag net 67, wire 68, magnet 69, wire 70, part of wire 51, contact-points, and one of the bridges of circuit-controller 48, which are of course always in their closed position when clutch 31 is energized, wire 55 to one side of reversingswitch 43; also from'push-button 95, through wire 84, wire 59, wire 45, to the other side of reversing-switch 43. By pressing upon pushbutton 95 the operator thus energizes releasing-magnet 67 along with magnets 62 and 69 and withdraws catch 94 from operative connection with circuit-controller 86, thus per- 'mittiug'that circuit-controller to fall back into its normal open position, breaking the circuit through clutch 31 and denergizing that clutch. It will of course be understood that circuit-controller 86, as well as circuitcontroller 72, is kept in its open position by springs or other suitable devices for that pur- IOO IIO

pose. The operator can thus at will by pressing push-buttons 90 and 95 cause clutch 31 to be energized or denergized, thus moving hoisting-arms 35 or causing them to stand still. The movement of the hoisting-arms upward or downward will depend upon the direction of rotation of the inotor.

By my improved devices rotation in one direction or the other can be imparted to the motor and the carriage be driven in one direction or the other upon the rails, as desired, and be stopped at any desired point thereon, and the hoisting-arms can be lowered or raised at will.

The devices for bringing printing-cylinders or printing-tubes or supports therefor to the carriage and hoisting-arms or for taking them away form no part of my present invention, and no devices for that purpose are here shown or described. They may be brought to or removed from the carriage and hoisting-arms by hand or by any suitable means.

By means of my improved devices printing-cylinders or printing-tubes or supports therefor for presses can be rapidly, readily, and conveniently handled and can be introduced into and removed from operative position in the press rapidly and conveniently.

My improved devices are of peculiar value in multicolor-presses, such as the one shown inthe drawings, or in any presses in which there are a` large number of printing-surfaces. i

In order to insure the stoppage of the carriage with certainty at any predetermined point upon the rails, I provide automatic means for breaking the circuit through the motor and through clutch 18. My preferred devices for this purpose consist of the following: At each point where I desire the carriage to stop for the purpose of introducing printing cylinders or tubes or supports into the press or for removing them therefrom I place a switch which can be so arranged that when tlie carriage reaches that point upon the rails the releasing-'circuit through the releasing-magnets will loe closed, the catches for the circuit-controllers 48, 7.2, and y86 will be withdrawn, and the circuits through the motor and the clutches be broken. 97 971L represent two of these switches for stopping the carriage while moving in one direction, one of them, 97a, being shown in its open or non-operative position and the other, 97, in its closed or operative position. Each of these switches connects by a wire 98 with the strip upon one of the rails, as shown with strip 40. On the other side each switch is adapted to be connected with the wire 99, which leads to a contact-point 100. A contact-point 101 on the carriage is adapted as the carriage' moves along the rails to make contact with the diterent contact-points 100. If it is desired, for example, to stop the carriage at the switch 97, that switch is turned into the operative position, (shown at 97 in Fig. I.) When the carriage reaches this point upon the rails,

contact-points 101 and 100 make contact with each other, and this closes a circuit through the releasing-magnets. This circuit is as fol- `lows: The switch 37, wire 38, strip 40, wire 98, switch 97, wire 99, contact-points 100 101, wire 102, wire 65, releasing-magnet 62, wire 66, releasing-magnet 67, wire 68, releasingmagnet 69, wire 70, part of wire 51, one set of contact-points and bridge of circuit-com troller 48, wire 55, to one side of reversingswitch 43, wire 42, strip 41, wire 39, to the other side of switch 37. In this way the releasing-magnets are automatically energized when the carriage reaches the desired stopping-point on the rails, the catches are withdrawn, and the circuit-controllers are opened to break the circuit through the electric motor and through the clutches, particularly clutch 18, thus insuring the immediate and automatic stoppage of the carriage at the desired point.

.that it will make contact with another contact-point on the frame of the press and close one break in a similar circuit through the releasing-magnets in order to cut oit' the power and to denergize clutch 31 and to do this automatically. In this same circuit I place a switch which can be opened or closed by hand as desired. If it is desired to have an automatic stoppage oi the hoisting-arms when they reach their highest point, the switch is closed. Otherwise it is left open. This switch is shown at 108 in Fig. 1 and is there shown in its open position. It it is desired to have such automatic stoppage, switch 108 is closed. My device to cause this automatic stoppage is as follows: 103 is an arm connected to one of the hoisting-arms and carrying a contactpoint 104, which is adapted to make contact when the hoisting-arm is in highest position with contact-point 105 on the framework of the carriage. Contact-point 104 is electrically connected with wire 10G, which connects with wire 44. Vhen contact-points 104 and 105 are in contact with each other, the following circuit is closed through the releasing-magnets 62, 69, and 67-namely, switch 37, wire 38, strip 40, wire 44, wire 106, contact-points 104 105, wire 107, switch 108, (when closed,) wire 109, wire 102, wire 65, magnet 62, wire 66, magnet 67, wire 68, magnet 69, wire 70,

part of wire 51, contact-points and bridge of circuit-controller 48, wire 55, wire 42, strip 41wire 39, to the other side of switch 37. By closing switch 108, therefore, the automatic stoppage of the hoisting-arms in their upward movement is assured.

In the preferred form of my invention a common circuit through releasing-magnets 62, 67, and 69 is used, although, if desired, separate rail-circuits through each magnet might be used. One advantage of having a common circuit is that upon pressing any one IOO IIO

of the push-buttons 61, 81, or 95 all of the releasing-magnets are energized and the power is shut off from the motor, and both the clutches are denergized, thus making the stoppage at the particular part desired the more certain. In this Way also the automatic stoppage of the carriage at any desired point upon the rails and the automatic devices for stopping the upward movement ot the hoist.- ing-arms also affect all three releasing-magnets and shut oit the power and denergize both clutches.

In Fig. 1 only the wires 50 and 5l running to the armature are shown, the wires running to the fields ot' motor 11 being omitted from that view.

In Fig. 6 I have shown the Wires running to the iields of the motor and their connection withzthe rest of the system. 110 is a wire running from one side of the iields of the motor connecting with main-line wire 44. 111 is a wire running from the other side of the fields of the motor connecting with an additional set of contact-points and bridge of circuit-controller 48-to wit, the top set of contact-points and bridge of that circuit-controller, Wire 112 running from the contactpoints and connecting with the other mainline wire 42. Thus every time the circuitcontroller 48 is closed or opened the circuit through the fields will be closed or opened irrespective of reversi ng-switch 43. By reversing the currents through the armature the motor may accordingly be driven in one direction or the other, as desired.

In the construction shown in Fig. 1 the devices t'or automatically stopping the carriage at any given point or forstopping the hoisting-arms when they reach their highest position are operated only when the reversingswitch is in one position and are not operated when the switch is in the other position. Automatic switches for stopping the carriage or the hoisting-arms when the switch is in the latter position can be inserted, it' desired, by merely connecting the switches with the op,- posite rail from that with which switches 97 and 97a (shown in Fig. 1) are connected. I prefer, howeveigto arrange the circuit so that but one set of switches need be employed, and I show this system in Fig. 6 as far as is necessary to make the same intelligible. This I accomplish by omitting Wire 70, running from magnet 69, and by running a wire 113 from that magnet directly to main-line wire 42, thus completing the circuit without passing through switch 43. The reversal of the switch therefore has no eliect upon lthe operation of the automatic devices. For the same reason I preferably connect wire 84 directly with main-line wire 44 by wire 114 instead of by wires 59 and 45, thus closing the circuits through push buttons 61, 81, and 95 without having the circuit pass through reversing-switch 43. In all other respects the circuits shown in Fig. 6 are like those shown in Fig. 1.
